Firstly, I need to correct a couple of comments ...
The X-Fi Xtreme Audio card is a host-based X-Fi card so some of the
filenames are different compared to a hardware-based X-Fi card.
Specifically, the native OpenAL device is stored in a DLL called
sens_oal.dll (not ct_oal.dll). This component is only installed on
Windows Vista (it is not needed on Win XP)
On Windows XP you can use the "Generic Hardware" device to get EAX 2,
3, 4 and EFX Extension support on the X-Fi Xtreme Audio card. (The
EFX Extension is available via "Generic Hardware" when ever the
soundcard supports at least EAX version 2.0. The EFX Extension is
also available (with an EAX 2.0 feature set) via the "Generic
I'm guessing you are using WinXP because you shouldn't have been able
to open the "Generic Hardware" device on Vista. Is that right?
Does the TAO Framework have support for the ALC_EXT_EFX ? I couldn't
tell from their website as it only mentions support for OpenAL 1.1.
If the TAO framework does include support for the extension, then I
would check to make sure that your Audio Hardware Acceleration Slider
is set to FULL. This can be found in the Sound and Audio Devices
panel from the Windows Control Panel.
